Poliwhirl is a Stage 1 Water Pokémon with 90 HP. In the Pokédex this is Poliwhirl (#061), generation 1 (Kanto). The card says it evolves from Poliwag. In this catalog that name is Poliwag (#060). The card lists Poliwrath, Poliwrath (#062) and Politoed, Politoed (#186) under evolves to.
Atsuko Nishida illustrated this card. The same name is on 408 other cards in the catalog.
Poliwhirl (#061) has 17 other cards in the catalog. Those other cards are in 16 sets. The other printings with a release date run from 1999 to 2024. The earliest other card is Poliwhirl 38/102 in Base (1999). That card lists 60 HP, and this one lists 90 HP. Both list the rarity Uncommon.

The cost is Water, Colorless, Colorless. Weakness is Grass ×2. Retreat cost is 2. The flavor text reads "It marches over the land in search of bug Pokémon to eat. Then it takes them underwater so it can dine on them where it's safe."
I keep a set binder for Sun & Moon, meant to hold every card of that set. This card is one slot in the Sun & Moon set binder. A generation binder holds one card of each species. Poliwhirl can fill a slot in Generation 1 binder (Kanto). Themed lists that include this exact card are Atsuko Nishida cards, later series. I still need this card.
